<p>Probabilities and statistics: they are everywhere, but they are hard to understand and can be counter-intuitive. So what's the best way of communicating them to an audience that doesn't have the time, desire, or background to get stuck into the numbers? This article explores modern visualisation techniques and finds that the right picture really can be worth a thousand words.</p>

<p>Do you think bungee jumping is riskier than smoking? Would you take a medicine with a 10% risk of serious side effects? Or board a plane with a 1% chance of crashing? Risk is a very complex topic, studied by researchers all over the world. In the Big Risk Test, which is now live as part of BBC Lab UK, we want to find out how people deal with risk, particularly to try and understand what makes people have such different opinions and feelings about life's chances.</p>

<h3>The notion of uncertainty</h3>
<p>In the early 19th century, the French mathematician <a href="http://www-history.mcs.st-and.ac.uk/Biographies/Laplace.html">Pierre-Simon de Laplace</a> wrote of a concept he had been thinking about for some time. The concept became known as <em>Laplace's demon</em> and was a thought experiment which sought to clearly explain the existence of uncertainty. It is described in his <em>Essai Philosophique sur les Probabilités</em> (1814) as:

Comparing and communicating small lethal risks is a tricky business, yet this is what many of us are faced with in our daily lives. One way of measuring these risks is to use a quantity called the micromort. <b>David Spiegelhalter</b> and <b>Mike Pearson</b> investigate. </div>
